RIO Cleanalytic Services performs the determination of particle size with an automatic particle analysis unit of JOMESA.
Routine cleanliness inspections are based on optical microscopy. Usage of polarisation filters enables the differentiation of metallic and non-metallic particles. But an oxidized welding bead (for instance) is specified as nonmetallic particle due to its non-metallic brightness caused by the oxide layer on the surface. In such cases, single particle analysis is executed to indetify the chemical nature of the particle. RIO Cleanalytic Services offers single particle analysis in form of energy dispersive X-ray spectroscopy (EDX).
